As we have already PIO 6 transfer mode supported in IDE layer, we can turn it on in the driver.

2009-04-08ide: refactor tf_read() methodSergei Shtylyov
Simplify tf_read() method, making it deal only with 'struct ide_taskfile' and the validity flags that the upper layer passes, and factoring out the code that deals with the high order bytes into ide_tf_readback() to be called from the only two functions interested, ide_complete_cmd() and ide_dump_sector(). This should stop the needless code duplication in this method and so make it about twice smaller than it was; along with simplifying the setup for the method call, this should save both time and space...

2009-04-08ide: simplify 'struct ide_taskfile'Sergei Shtylyov
Make 'struct ide_taskfile' cover only 8 register values and thus put two such fields ('tf' and 'hob') into 'struct ide_cmd', dropping unnecessary 'tf_array' field from it.

2009-04-08ide: Fix host drivers that need IRQF_SHAREDGeert Uytterhoeven
commit 255115fb35f80735c21a1cbe9809e9795a3af26e ("ide: allow host drivers to specify IRQ flags") added irq_flags fields to struct ide_port_info and struct ide_host. Drivers can now set ide_port_info.irq_flags = IRQF_SHARED, while init_irq() passes ide_host.irq_flags to request_irq(). Unfortunately ide_host.irq_flags is never set, causing (on ARAnyM): | Uniform Multi-Platform E-IDE driver | ide: Falcon IDE controller | Probing IDE interface ide0... | hda: Sarge m68k, ATA DISK drive | init_irq: sa = 0 | ide0: disabled, unable to get IRQ 15 | ide0: failed to initialize IDE interface | ide0: disabling port Solve this by copying ide_port_info.irq_flags to ide_host.irq_flags in ide_host_alloc().
